"Spamalot” creator Idle (4)
I believe the answer is:
eric
'spamalot creator idle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eric that I've seen before include "Rice turned for the boy" , "One of pair once popular" , "..... the Red was Norwegian 10th Century exployer" , "Boy's name" , "- the Red, discoverer of Greenland" .)
